Delocalised Electron - GCSE Chemistry Definition

Reviewed by: Philippa Platt

Last updated

A delocalised electron is an electron that is not associated with a single atom or a single covalent bond within a molecule; rather, it is free to move across several atoms. This is common in metals and certain types of structure including graphite.

In metals, delocalised electrons can move easily through the structure, which is why metals can conduct electricity and heat.

Understanding delocalised electrons is important at GCSE level because it helps explain various physical and chemical properties of substances.
